And on this side of the pond at 120 volts...the 600 watts is about 6 Amps and that is a really small micro. To deliver even 50 amps DC from your batteries to an appliance would require some major cabling. For 750 watts you need 6 guage cable for less than a 10 foot run in one direction.

Stick with AC!

Thanks for all your replies.

Cam,
AC is not an option. Raven isn't wired for it, we don't carry a generator and very rarely do we tie up to a dock. Your comments are all concerns that were rattling around in my head. As was Chris's comment re gimballing. An MW is not something we use a great deal even at home but madam thinks on Raven it would come in handy. Defrosting is not an issue cos we don't have a freezer, really the only thing it would be used for is heating liquids and maybe reheating leftovers. Not worth the hassle methinks.

Cheers

TD
